Homemade Marshmallow Fluff Ingredients
For the Fluff
• Water – Provides moisture and helps dissolve sugar.
• Granulated Sugar – The main sweetener that gives the fluff its delightful texture.
• Light Corn Syrup – Adds sweetness and prevents crystallization for a smooth finish.
• Egg Whites – Create volume and structure; ensure they are at room temperature for optimal whipping.
• Cream of Tartar – Stabilizes egg whites when whipped, maintaining that beautiful fluffy texture.
• Vanilla Extract – Enhances flavor; you can substitute with almond extract for a unique twist.
Step‑by‑Step Instructions for Homemade Marshmallow Fluff
Step 1: Combine Ingredients
Start by pouring water, granulated sugar, and light corn syrup into a medium heavy-bottom saucepan. Place the saucepan over medium-high heat while allowing the mixture to come to a gentle boil. Avoid stirring at this point, as you want the sugar to dissolve fully, creating a clear syrup. Monitor closely for about 5–7 minutes until the mixture reaches 240°F; a candy thermometer will show when it’s ready.
Step 2: Whip Egg Whites
As the syrup reaches temperature, grab a mixing bowl and add in your egg whites alongside the cream of tartar. Using an electric mixer, beat the mixture on medium speed for about 3–4 minutes until soft peaks form. You’ll know they’re ready when the whites hold their shape but still droop slightly. This whipped mixture is the airy foundation for your homemade marshmallow fluff.
Step 3: Combine Syrup and Egg Whites
Once the syrup hits 240°F, slowly pour the hot mixture into the whipped egg whites while continuously whisking at medium speed. It’s crucial to do this gradually to prevent the egg whites from cooking. Keep pouring until the syrup is fully integrated, which should take about 1–2 minutes.
Step 4: Whip Until Thickened
After incorporating the syrup, increase the mixer speed to medium-high. Continue to whip the mixture for roughly 7–8 minutes or until it thickens and becomes glossy. You’ll notice the marshmallow fluff starting to hold its shape and nearly double in volume, transforming into a delightful, airy treat with a cloud-like texture.
Step 5: Add Vanilla Extract
With the fluff adequately whipped, gently mix in vanilla extract to enhance its flavor. Simply fold it in using a spatula, ensuring it’s evenly distributed throughout the fluffy mix. This final touch will elevate the taste of your Homemade Marshmallow Fluff, rounding out its sweetness perfectly.
Step 6: Cool and Store
Once mixed, transfer the fluff to an airtight container. Allow it to cool completely to room temperature before sealing. This luscious marshmallow fluff can be stored at room temperature for up to two weeks, ready to enhance your desserts, from frostings on cakes to cherished childhood fluffernutter sandwiches.

Expert Tips for Homemade Marshmallow Fluff
• Grease-Free Preparation: Ensure all mixing bowls and tools are thoroughly cleaned with vinegar or lemon juice. This keeps the egg whites fluffier by avoiding any grease.
• Room Temperature Eggs: For the best volume, use egg whites at room temperature. This will help your fluff achieve that dreamy, airy texture.
• Careful Syrup Monitoring: Watch the sugar syrup closely while it cooks. If it cooks too long, it can burn—trust your thermometer to gauge the 240°F mark!
• Pouring Technique: When combining the syrup into the whipped egg whites, pour it slowly. This helps maintain the fluff’s airy structure and prevents cooking the eggs too quickly.
• Whipping Duration: Don’t rush the whipping process after pouring in the syrup. It usually takes about 7–8 minutes to achieve the right glossy, thick consistency for your Homemade Marshmallow Fluff.
• Storage Tip: Store your marshmallow fluff in an airtight container to keep it fresh for up to two weeks. It’s best enjoyed at room temperature, so let it warm up a bit before using.

Homemade Marshmallow Fluff Recipe FAQs
How do I choose the right egg whites?
Absolutely! For the best results, use fresh egg whites that are at room temperature. Room temperature allows them to whip up to their maximum volume, ensuring your marshmallow fluff achieves that delightful, airy texture. If you can’t see yourself using fresh eggs often, consider using pasteurized egg whites from a carton—just make sure to follow the equivalent measurement for the number of eggs you need.

How should I store leftover marshmallow fluff?
Very important! Store your homemade marshmallow fluff in an airtight container at room temperature for up to 2 weeks. If you want to keep it for longer, you can refrigerate it for up to 3 weeks—just remember, it might become a bit thicker, so allow it to warm to room temperature before using.
Can I freeze homemade marshmallow fluff?
Absolutely! For freezing, place the fluff in a freezer-safe container, leaving space for expansion, and it can last up to 6 months. To use, thaw it overnight in the fridge and then re-whip or lightly heat it in the microwave for 5-10 seconds if needed. This will help restore its texture before serving.
What should I do if my marshmallow fluff isn’t thickening?
If your mixture isn’t thickening, it could be due to a couple of factors. First, ensure your syrup reached 240°F; if it didn’t, it won’t whip properly. Secondly, check that your mixing bowl and whisk are completely grease-free, as any fat can hinder the egg whites from reaching their full volume. If it still seems too runny, keep whipping for an additional minute or two—it can often surprise you!
Can pets have marshmallow fluff?
It’s best to keep marshmallow fluff away from pets. While the ingredients are not toxic, fluff is high in sugar and not suitable for animals, especially cats and dogs. If your pet has a tendency to sneak food, be careful not to leave it out where they can reach it!
Are there any allergy considerations for this recipe?
Of course! The main allergens in homemade marshmallow fluff are eggs and potentially corn from the corn syrup. For egg allergies, consider using aquafaba (the liquid from canned chickpeas) as a substitute—just whip it until stiff peaks form similarly to the egg whites. If you have a corn allergy, you can use a sugar substitute like maple syrup but be prepared for a different flavor and consistency.
